SPECIFICATION forming part of Letters Patent No. 279,271, dated June 12,1883.

' Application filed February 13, 1883. (No model.)

To all whom it may concern:

Be it known that we, FREDERICK E. OKIE, of Linwood, in the county of Delaware, and .I. FOURESTIER SIMPSON, of the city and county of Philadelphia, both in the Stateofv Pennsylvania, have invented a new and useful Improvement in WVrenches, of which the follow ing is a specification.

The object of our invention is to furnish a wrench which may be used in contracted places without the necessity of removing thej aws from the nut; and we accomplish this object by the use of a ratchetwheel and pawls, whose par ticular arrangement and construction will be more fully described hereinafter.

I11 the accompanying drawings, forming part of this specification, and in which similar letters of reference indicate like parts throughout the several views, Figure'l represents a side view of our invention; Fig. 2, a side view of the outer end of the shank of our wrench, showing the shaft upon which the jaws revolve; Fig. 3, a top view of the guide upon which the jaws travel; Fig. 4, a side view of one of the jaws; Fig. 5, an end view of the same; Fig. 6, a side view of the ratchet and pawls; Fig. 7, a modification of our invention, and Figs. 8, 9, 10, and 11 details of the same.

The shank A of our wrench has at right angles to its outer end a shaft, B, upon which the guide 0, which carries thejaws, revolves. This shaft also carries upon it a ratchet-wheel, D, which is keyed fast to the shaft, and works in a slot in the guide 0. Above and below the ratchet-wheel, and gearing into it," are two p'awls, E F, which work on shafts passing through the guide C, and these pawls are operated by thumbscrews G, which are carried upon a beam, I, which spans-the slot in the guide in which the ratchet-wheel works. Upon the pawls are springs H, through which the thumb-screws pass, and by turning these screws the pawls may be elevated or depressed.

Fig. 4 shows a side view of one'of the jaws of our wrench, from which it will be seen that they have a square slot, L, at one end, through which the guide 0 passes.

Fig. 5 represents I a view of the. end of the jaws next the shank, from which it will be seen that they are hollowed out, so as to allow the jaws to pass over shaft B and come together.

In operating the wrench the jaws are placed over the nut that is'to be tightened or loosened,

and the proper pawl thrown into action with the ratchetwheel. The handle is now moved back and forth, and as the pawl and ratchet only engage upon being moved in one direction, the nut can be completely removed or screwed down without removing the jaws from it.

In Fig. 7, which represents a side view of a modification of our invention, the shank A is bifurcated at its end to receive the ratchet wheel D. This ratchet-wheel is carried upon a shaft, B, which also carries the jaws J J.

The arrangement of the pawls and ratchetwheel in this modification is shown in Fig. 8, and two devices for controlling the pawls are shown in Figs. 9 and 10. The device shown in Fig. 9 consists simply of a collar, M, slipped over the shaft B and resting on the face of the shank A. This collar is preferably of the shape shown in the drawings, and when it is turned it forces out one of the pins (1, which are carried upon the pawls and move in slots in the face of the shank.

The device shown in Fig. 10 consists of a collar, b, which encircles the shaft B, and has appropriate faces for operating the pins (1. and a shank, 11, extending down the shank of the wrench. This shank d is secured to the shank of the wrench by clips 0 c, and it is furnished with a screw, f, by means of which it may be secured at any place. In the drawings the collar is represented as being down and the lower pawl is out of action. If, now, the collar is thrown up, it will raise or force out the pin upon the upper pawl, and this will be thrown out of action andthe lower one will be thrown in. If the collar is placed between the pins, both pawls are thrown into action and the wrench becomes a solid one. If it be desired to revolve the jaws of the wrench without turnratchet-wheel D, consisting of the springs H ing the handle, both pawls are thrown out of on said pawl, and set-serews G G, passing 15 action, and the milled head N on the shaft B is through said springs, and being carried upon turned with the fingers. beams I I, spanning the slot or bifurcation in 5 Having thus described our invention, we which said ratchet-whee], works, substantially claim and desire to secure by Letters Patent as set forfln 1.
